sprockets 15, and plates 88 form guide slots rest upon the serrations 25, as they travel downwardly in the corresponding hoppers. By this arrangement it will be observed that a large number of plates 23 may be arranged and stacked in the respective hoppers to form a large number of different signs, and said plates will be automatically Withdrawn from said hoppers, arranged to form the various signs and then automatically discharged into the hoppers again.

in order to etlect discharge of the sign plates 23 from the casing 11 for changing of the signs, guide lingers 41 are arranged as indicated on a shaft 41 having an operating handle 42 provided with a lock pin 43 adapted to engage one of a plurality of lock holders 44 formed in the casing 11, as indicated. The guide fingers 41 arearranged to constitute the upper rear portions of the slots 40 when positioned as shown in Figs. 2 and 8 or to be elevated. as indicated by dotted lines in Fig. 2, or depressed into the position shown in Fig. 10 to effect discharge of the plates. To facilitate entry or discharge of the plates 23, guide plates 45 are positioned to cooperate with plates 38 and 20 to form slots 4G and 47, slots 46 constituting rearward tangential. prolongationvo'f slots40 and slots 47 constituting entry slots for the rod ends 22. leflecting leaves or plates 48 are secured t0 a shaft 49 in positions to be swung downwardly to rest upon lugs 48 to constitute deflectors to further assist the discharge of the plates 23. Shaft 49 is equipped with an operating handle 50 carrying a lock pin 51 to facilitate manipulations thereof, and discharge slots 5'2 are provided to permit the discharge of the plates 23. By this arrangement when it is desired to discharge the sign plates, the

fingers 41 are depressed and the deflector plates 48 are swung downwardly whereupon the sign plates will be automatically discharged by the automatic action of the mechanism. rllhe newly arranged sign plates are inserted from the top, the ends of the rods Q2 traveling in the slots 47, for which purpose both the fingers 4l and the deliector plates 48 are elevated. Suitable electric light bulbsk 53 are arranged in the casing 11, as indicated, :for illuminating purposes. j

Tifhile i have illustrated and described the preferred torni of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. lf, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. insign comprising a conveyer; sign members on said conveyor; and manually controlled means for automatically discharging said sign members, substantially as described.

Q. A sign comprising a plurality of adjacent conveyers; letter sign members on each of said conveyers cooperating with those on the others to complete a sign; `means for automatically removing said sign members from said conveyers and stacking them in piles; and means for automatically removing the bottommost sign members from said piles and remounting them on said conveyers, substantially as described.

3. A sign comprising a plurality of adjacent conveyors; sign members on each of said conveyers cooperating with those'on the others to complete a sign; and manually controlled means for automatically discharging said sign members, substantially as described.

4. A sign comprising a plurality of adjacent conveyers; sign members on each of said conveyers coperating with those on the others to complete a sign; means on said conveyers for automatically discharging and rengaging said sign members; and manually controlled means for automatically discharging said sign members, substantially as described. l

5. A sign comprising a plurality of adjacent conveyers; sign members on each of said conveyers cooperating with those on the others to complete a sign; means for automatically removing said sign members from said conveyers and stacking them in piles; means for automatically removing the bottommost sign members from4 said piles and remounting them on said conveyers; and manually controlled means for automatically discharging said sign members, substantially as described.

6. A sign comprising a casing; two parallel shafts in said casing one above the other; a plurality ot pairsof sprocket wheels on said shafts; sprocket chains traveling over said sprocket wheels; transversely alining lugs on said sprocket chains; hoppers in said casing corresponding with said pairs of sprocket chains; sign letter plates arranged in piles in said hoppers; laterally projecting pins on said plates, there being guide slots for said pins arranged to guide said plates, the slots arranged to guide said plates during their travel through said hoppers being zigzag in form; a zigzag guide for the edges of said plates opposite said pins; traveling chain conveyers located under each of said hoppers; and lugs on said last mentioned conveyers arranged to engage the pins on the bottommost sign members in said hoppers and carry said bottommost sign members in operative relation with the lugs on said first mentioned sprocket chains, substantially as described.

'7. A sign comprising a casing; tvvo parallel shafts in said casing one above the other; a plurality of pairs of sprocket Wheels on said shafts; sprocket chains traveling over said sprocket wheels; transversely alining lugs on said sprocket chains; hoppers in said casing corresponding with said pairs of sprocket chains; sign letter plates arranged in piles in said hoppers; laterally projecting pins on said plates, there being guide slots for said pins arranged to guide said plates, the slots arranged to guide said plates during their travel through said hoppers being zigzag in form; a zigzag guide. for the edges of said plates opposite said pins; traveling chain conveyers located under each of said hoppers; lugs on said last mentioned conveyers arranged to engage the pins on the bottommost sign members in said hoppers and carry said bottommost sign members in operative relation with the lugs on said first mentioned sprocket chains; and a manually controlled deliector arranged to engage and discharge said sign members from said casing, substantially as described.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing Witnesses.
